Is it possible to customize the theme?

This software is great, I would like to personalize it as I like to use on my daily workflow :slight_smile:
I would basically like to change some colors and the logo image shown. Is this possible?

Logo: Edit > Settings > Application UI > Logo file
Be careful with the logo image size, its height should be ~50 pixels. Otherwise the timeline becomes as tall as image.

Application colors ar enot customizable, sorry, You can choose one of the appearances in Edit > Settings > Application UI > Appearance.

Thank you, I’ve tried the GTK+ theme, but unfortunately doesn’t change background color of the charts. Also, is there a way to edit the config outside the program? I tried to change the DPI option and how I cannot see anything and there is no way to revert it…

The config sits in .ganttproject file in your home directory.

I’ve done some testing, and the logo needs to be 47px high so that it does not resize. My logo was 47px height x 347px width which rendered correctly. I’m sure 347 is slightly too wide, but GanttProject does not seem to try and squash it up.
